The aim of the study was to investigate the decontamination of pig slurry containing exotic viruses of pigs, foot AND mouth disease virus (FMDV), Aujeszky's disease virus (ADV) AND classical swine fever virus (CSFV). Laboratory-scale decontamination experiments showed that FMDV, ADV and CSFV were heat inactivated in slurry within 3 min at 67 degrees C, 3 min at 62 degrees C and 3 min at 60 degr...

Microbial consortia isolated from aged oil-contaminated soil were used to degrade 16 polycyclic aromatic hydrocarbons (15.72 mgkg(-1)) in soil and slurry phases. The three microbial consortia (bacteria, fungi and bacteria-fungi complex) could degrade polycyclic aromatic hydrocarbons (PAHs), and the highest PAH removals were found in soil and slurry inoculated with fungi (50.1% and 55.4%, respec...

In this paper, we present a review of the measurements that Dual Emission Laser Induced Fluorescence (DELIF) has allowed us to make over the last 8 years. We have been able to measure many features of the slurry film between the wafer and the pad during polishing while simultaneously measuring the frictional drag. In particular, we measured slurry mean residence time, slurry temperature, and th...

Stainless steel pipe with fine hole and long size has recently been needed for the flow line of pure gas and liquid, which is used in the field of precision machinery. Inner wall polishing of the capillary is very difficult by ordinary finishing methods. High speed slurry flow finishing method developed by authors has been proved to have excellent polishing performance, but it has been needed a...

To utilize a super-hydrophobic tetradecane-adsorbed marshmallow-like gel as phase-change material (PCM) carrier for latent heat transportation by mixing the particles with sodium carboxymethyl cellulose (CMC) solution, dispersion characteristics and flow of slurry were investigated. investigate slurry, visual observation under static conditions was performed while varying concentration CMC, app...

Understanding P sorption from animal manures is essential to formulate best management practices with regard to land application of manure from the standpoint of crop production and environmental quality. Little research has focused on the construction of P sorption isotherms where the P source is manure. The objectives of this study were to: (i) develop a procedure to characterize how inorgani...

AND CONCLUSIONS Chemical Mechanical Planarization (CMP) must continuously improve to meet the stringent requirements of next generation IC device manufacturing. Precision flow control of CMP slurry is critical to achieving a repeatable planarization process, minimizing slurry waste, and reducing cost-of-ownership (CoO). Monitoring and controlling slurry large particle concentration through filt...

Because of intensive animal farming, the problem of animal wastes disposal has become very acute in the Reunion Island, namely for liquid wastes such as pig slurry. In this paper we address the problem of determining efficient supply policies of a slurry treatment plant collectively managed by individual farmers. For this, we built a simulation model with a continuous part (i.e., slurry stocks ...

In the present configuration of livestock manure management, and particularly for the pig industry, slurry is collected from barns and stored into storage tanks inside and/or outside of livestock buildings before spreading. During this storage period, in anaerobic condition, production and accumulation of sulphur (S) compounds occur. Among the molecules produced, some are of particular concern ...
